我在测试环境中没有注意到这个错误我应该检查什么？

我正在使用ASP.NET MVC 2(候选发布者2)

我的项目(UI层是asp.mvc)是使用.NET 3.5开发的.升级到.NET 4.0后,我遇到了编译查询的问题:

 [ArgumentException: Query was compiled for a different mapping source than the one associated with the specified DataContext.]
   System.Data.Linq.CompiledQuery.ExecuteQuery(DataContext context, Object[] args) +863348
   System.Data.Linq.CompiledQuery.Invoke(TArg0 arg0, TArg1 arg1) +110

每当我运行我的查询时,我都会传递我的上下文

return StaticQueries.getTopFiveOrders(mContext, int howMany);


public static Func<Mycontext, int, IQueryable<Order>> getTopFiveOrders
            = CompiledQuery.Compile
                ((Mycontext mContext, int howMany) =>
                 ( some query).Distinct());

第二个请求发生错误.

我正在寻找使用群体智能有效地算法的实际问题(或实现,应用程序)示例.我发现多标准优化就是一个例子.还有其他人吗？

应该将恕我直言的群体智能添加到标签中

安装 net6 Preview 3 并将项目设置为使用 net6 后，我更改了 launchSettings.json 并添加了 "hotReloadProfile": "blazorwasm"配置。

当我运行dotnet watch项目启动时，但由于客户端错误（dotnet.6.0.0-preview.5.21301.5.js），我无法打开应用程序：

System.AggregateException: One or more errors occurred. (Failed to fetch dynamically imported module: https://localhost:5555/_framework/blazor-hotreload.js

还应该更改哪些内容才能启用热重载功能？

我想将二维搜索空间中的某个点移动到具有一些步长的另一个点b(_config.StepSize = 0.03).

Point a = agent.Location;
Point b = agentToMoveToward.Location;

//---    important        
double diff = (b.X - a.X) + (b.Y - a.Y);
double euclideanNorm = Math.Sqrt(Math.Pow((b.X - a.X), 2) + Math.Pow((b.Y - a.Y), 2));
double offset = _config.StepSize * ( diff / euclideanNorm );

agent.NextLocation = new Point(a.X + offset, a.Y + offset);
//---

这是对的吗？
